When Dolby released Atmos, it was done in concert with their surround upmixer which does a great job enhancing 2CH music thanks to a key feature Dolby is now removing from new products. We don't understand why "center spread' is being eliminated but implore you to voice your concerns to Dolby and your favorite receiver manufacturer if you feel this to be an important feature for your music playback enjoyment . Perhaps we can all be part of a collective voice to persuade Dolby to reverse this decision so we can all enjoy the benefits of our multi-channel speaker system for our 2CH music sources.

Feedback is an ubiquitous and unavoidable basic technique that keeps the world running. It is only controversial in consumer audio, and then only specifically in power amplifiers. Some audiophiles believe too much negative feedback will diminish sound quality in amplifiers while others believe no feedback is even better. Is any of this true or is it just another audiophile myth needing to be busted?

It’s looking like 2020 will be the year that the high-end LCD TV meets its end. Like CRT and plasma TVs in years past, LCD TV is reaching the end of its life, at least in the high-end market.

Let’s explore the difference between acoustic suspension and sealed and see if today’s designers aren’t missing an opportunity to make some great products.
